Definitions

  • the present invention concerns a blanket cylinder for an intaglio printing machine comprising at least a plate cylinder carrying printing plates with engravings corresponding to a specific intaglio structure to be printed on a substrate, and cooperating with an impression cylinder carrying a substrate to be printed, the blanket cylinder having at least one blanket on which the ink in the different colours is deposited by selector cylinders, each selector cylinder receiving ink of a given colour and having reliefs with contours corresponding to the area of the intaglio structure to be inked with said given colour.
  • the present invention also concerns an intaglio printing machine with a blanket cylinder.
  • Intaglio printing machine are known in the prior art, especially for the printing of securities such as bank-notes and other similar objects.
  • US patent 5,062,359 discloses a sheet-fed or web-fed intaglio printing machine.
  • This machine comprises a plate cylinder with several printing plates, an impression cylinder, a wiping device and an inking system with a collector inking cylinder, having an elastic surface, interacting with the printing plates, with selective inking cylinders having reliefs corresponding to the coloured zones to be printed in different colours and in contact with the periphery of the collector inking cylinder, and of an inking device associated with each selective colour inking cylinder.
  • the inking system comprises a plurality of selector cylinders which are used for transferring the ink in a given colour from the inking units onto the collector cylinder, which in turn inks the engravings of the plates.
  • Each selector cylinder has a hard surface, for example surfaces lined with hardened rubber, plastic or the like, or metal, each selector cylinder comprising relief areas having contours corresponding exactly to the contours of the surface to be printed with the corresponding colour.
  • a problem which is present in this field resides in the fact that the inking of the intaglio structure, in particular of the plates is not precise, therefore ink is transferred on a larger area than the effective intaglio structure, this ink being later wiped away by the wiping system. Accordingly, a high quantity of ink is lost because it is deposited outside the places effectively corresponding to engravings of the plates, and is then wiped away without being used for inking the plates.
  • Another aim of the present invention is to reduce the quantity of ink necessary for the printing without diminishing quality of the printing.
  • a further aim of the present invention is to improve preciseness of the inking of the plate cylinder by the collector or blanket cylinder.
  • one uses the ink separating process of lipophilic and hydrophilic structures and one then engraves this structure on the blanket, which corresponds exactly to a metal plate.
  • the blanket is lipophilic and covered with a lipophobic/hydrophilic engravable surface, hence achieving a very precise inking of the plate.
  • the blanket has to be redone as soon as the elongation of the metal plate creates uninked fine lines.
  • a second embodiment uses the ink separating process of lipophilic and hydrophilic structures and engrave this structure on the blanket, which corresponds exactly to the metal plate.
  • the blanket is lipophobic/hydrophilic and covered with a lipophilic engravable surface, hence achieving a very precise inking of the plate.
  • the blanket has to be redone as soon as the elongation of the metal plate creates uninked fine lines.
  • one uses the ink separating process of typography and one engraves the desired structure on the blanket, which corresponds exactly to the metal plate.
  • the blanket is covered with a lipophilic engravable surface, thus achieving a very precise inking.
  • the blanket has to be redone as soon as the elongation of the metal plate creates uninked fine lines.
  • a first process is a varnishing process in which the layers are successively added on a base layer.
  • Another process that can be used is a laminating process.
  • a further known process is a sol-gel process, as known under the tradename ORMOCER®e of the Fraunhofer Institut Silicatforschung (see for example the web pages published on the internet at the address www.isc.fhg.de). With the disclosed process, it is possible to build the layers of lipophilic and/or hydrophilic materials according to the invention.
  • the principle of functioning of an intaglio sheet-web or web-fed printing machine is described first with reference to figure 1, with the different cylinders rotating in the direction shown by the arrows.
  • the following description of the printing is given for a sheet-fed printing machine, however the same principles apply also to a web-fed printing machine.
  • the sheets 1 arrive from a feeding system (not shown) and are transferred by a transfer cylinder 2 onto an impression cylinder 3.
  • the sheets are held on this impression cylinder 3 by grippers 4 for the impression process, said grippers being placed in cylinder pits 5.
  • the impression cylinder 3 has two segments each supporting one sheet to be printed.
  • the impression cylinder 3 cooperates with a plate cylinder 6, both cylinder 3 and 6 forming a printing nip in which the sheet receives the intaglio printing.
  • the plate cylinder 6 carries three plates in the example of figure held by gripping systems (not shown) placed into plate cylinder pits 7.
  • the plates as is known in the art of printing, carry engravings corresponding to the design to be printed, and the engravings of the plates further receive the ink, which is being deposited on the successive sheets.
  • the blanket cylinder 8 also called collector cylinder, which is used to ink the plates of the plate cylinder 6.
  • the blanket cylinder 8 carries three blankets 9.
  • the blanket cylinder 8 has a smooth surface forming the blankets 9 and receiving ink from selector cylinders 10 distributed along the periphery of the blanket cylinder 8.
  • selector cylinders 10 are inked in a given colour by an inking device.
  • the selector cylinders 10 have a surface which is harder than the surface of the blanket cylinder 8 and their surface is divided into sections with reliefs areas having contours corresponding exactly to the contours of the engravings of the plates which are destined to receive the ink of each respective selector cylinder 10.
  • each selector cylinder 10 is associated with an inking device comprising at least a duct roller 11, ink transfer rollers 12, an oscillator roller 13, an inker 14 containing the ink of a given colour and a drive 15 for driving the selector cylinders 10.
  • the ink contained in the inker 14 is transferred from the duct roller 11 to the selector cylinder 10 through ink transfer rollers 12 and then from the selector cylinder 10 onto the plate cylinder 6.
  • the excess of ink on the plate cylinder 6 is further wiped away by wiping cylinder 17.
  • the sheets 1 Once the sheets 1 have passed the printing nip and received the ink, they are taken away from the impression cylinder, for example by a delivery cylinder 16 for further treatment.
  • the blanket cylinder 8 has a base layer 30 on which a lipophilic layer 31 is deposited. Further, over the lipophilic layer 31, an engravable lipophobic layer 32 is deposited. Finally, a structure 33 which corresponds exactly to the shape of the engravings of the plates to be inked is created over the lipophobic layer 32 in order to receive the ink from the selector cylinders 10.
  • the structure 33 is, for example, created in the following manner.
  • the inking cylinder is inked completely with a selector cylinder and the ink is then transferred to the plate.
  • the plate is wiped, for example by wiping cylinder 17 (figure 1), to remove the ink excess of the plate.
  • the inked image of each plate of the plate cylinder 6 is then transferred to the collector cylinder 8 by rotation of the cylinders 6 and 8 with no substrate, i.e. paper, between them passing the printing nip thus forming the structure 33 shown in figure 2A and 2B, which corresponds exactly to the engravings to be inked on the plates of the plate cylinder 6, in perfect register.
  • the lipophobic layer 32 is removed by appropriate means, for example as shown in figure 2B by a laser 34, or other equivalent means, to expose the lipophilic layer 31 between the structure 33. Therefore, as shown in an exaggerated way in figure 2B, the ink 35 is repelled by the lipophobic layer 32 and is accumulated in the exposed lipophilic structure of the layer 31 thus improving the preciseness of the inking of the engravings on the plate cylinder 6 by the blanket cylinder 8 and, by way of consequence, reducing the quantity of ink wiped away by the wiping cylinder 17 (see figure 1).
  • the layers forming the surface of the blanket cylinder 8 are made of a base layer, of a lipophobic layer 36 and of a lipophilic engravable surface layer 37 on which a structure 38 which corresponds exactly to the shape of the engravings of the plates to be inked is created.
  • the structure 38 may be created in the same way as structure 33 (see above).
  • the lipophilic layer 37 is removed except under the structure 38, thus exposing the lipophobic layer 36 that repels the ink on the structure 38. This effect accordingly improves the preciseness of the inking of the intaglio plates.
  • the blanket cylinder 8 comprises a base layer 30 on which a lipophilic layer 40 is deposited, this lipophilic layer 40 further supporting a structure 41 corresponding to the shape of the engravings of the plates to be inked.
  • the lipophilic layer 40 is further engraved by appropriate means, for example a laser 34, or other suitable equivalent means, to remove a part of the layer 40 between the structure 41 as shown in figure 4B.
  • the materials used as a lipophilic and hydrophobic material include but are not limited to rubber compositions, silicate compositions, and as lipophobic material include silicon compositions, rubber compositions.
  • these materials are given by way of examples and other equivalent materials with appropriate characteristics are possible to carry out the present invention.
  • Other examples are given by the sol-gel process, as known under the tradename ORMOCER®e, of the Fraunhofer Institut Silicatforschung (see for example the web pages published on the internet at the address www.isc.fhg.de) mentioned above.
  • the engraving operation of the blankets is made with the blanket cylinder 8 mounted in the printing machine in order to maintain a perfect register between the blanket cylinder 8 and the plate cylinder 6 once the structure 33, 38 or 41 has been created on the surface of the blanket cylinder 8.
